Lipoarabinomannan-based Tuberculosis Diagnosis using a Fiber Cavity Ring Down Biosensor
Ubaid Ullah, Seerat Saleem, Muddassar Farooq +2
Despite existing for millennia, tuberculosis (TB) remains a persistent global health challenge. A significant obstacle in controlling TB spread is the need for a rapid, portable, s…
Raman Spectroscopy and Machine Learning-based Optical Sensor for Rapid Tuberculosis Diagnosis via Sputum
Ubaid Ullah, Zarfishan Tahir, Obaidullah Qazi +2
Tuberculosis (TB) is a contagious disease that causes 1.5 million deaths per year globally. Early diagnosis of TB patients is critical to control its spread. However, standard TB d…
Phase shift-cavity ring down spectroscopy in linear and active fiber cavities for sensing applications at 1550 nm
Ubaid Ullah, M. Imran Cheema
Liquid phase sensing applications at 1550~nm are highly desirable due to widely available off-the-shelf components. Generally, liquids at 1550~nm induce a high absorption loss that…
Detection of Aflatoxin M1 by Fiber Cavity Attenuated Phase Shift Spectroscopy
M. Daniyal Ghauri, Syed Zajif Hussain, Ubaid Ullah +4
Aflatoxin M1 (AFM1) is a carcinogenic compound commonly found in milk in excess of the WHO permissible limit, especially in developing countries. Currently, state-of-the-art tests…
